. Application led July 18,

This invention relates to` pipe-working tools and more particularly todevices for cutting grooves in the l, periphery'of pipes andthe like;and it Aisamong the objects of the invention to provide a tooladaptableto loperate on various sizes .of.p1pe1tvbe1ngreadilychangedfrom one size to another. A'efurther object' is thek provision of'anaccurately controlled cutter feed. `Other olOeCtsV andadvantageswillappear as the descrip! tion proceeds. a l Y.

Any change of adjustment subsequently required may`be similarly made. Ordinarily the` first set screw 27 is held againstmovement by the second set screw 32; however in order to Lcompensate forwear of the cutter and the like, suoli second set screw may be turned torelease the ifirst, and the latter may then be adjusted for such slightt-ake-up in one di-y rection or the other as may be required.

of its movement against the stopQZ as setl for that size of pipe, andthereupon vthe grooving is completed. The cutterl is then run back andthe pipe removed .and another piece of pipe is brought into position.

As will thus be seen, the device as a whole presents a versatility ofapplication as regards sizes of pipe or the like operable upon, andadjustments to any `given size may be quickly made. Compensation Yforwear, etc., may also be had in a simple and accurate manner, and withal,the feeding of the cutter is characterized by positiveness andsimplicity'ot1 operation which makes for serviceabilityl and durableresults.

'Other modes of applying the" principle of the invention may beemployed, change being lmade as regards the details disclosed',

provided the means stated in any'of the following claims, or theequivalent of such, be employed.

I therefore particularly pointout and distinctly claim as myinvention 1. In a device of the character described, the combination ofan annular body member; work-centering means carried thereby; an annularhead rotatably mounted on said body member; a radialguideway on saidhead; a sleeve slidably mounted in said guideway; a lcutter carried bysaid sleeve; a feed screw engageable within a threaded bore inl saidsleeve; a bracket externally of said guide on. the rotatable head; abearing bushing journaled in said bracket, vthe outer portion of saidfeed screw beingV journaled in turn in said bushing; .an operating handwheel on ifzovfive the outer end of said feed screw; a stop including alieadprojecting into the path of said cutter-carrying sleeve; a guidefor said stop adjacent the sleeve; andineans forrad- 'ustabl settinevsaid sto a. In a device of the character described,

grooves, said stem being flattened on one side to .allow of axialadjustmentrelativ@J to the locking eiement, and a binding shoe and setscrew operating thereagainst.;y for 'holding the locking element inadjusted Aposition. v

3. In combination with disk-like member having a radial guidewaytherein, a vsleeve reciprocably mounted in said guideway, asecondguideway adjacent and parallel to said irst guideway,v a rodreciprocably mounted in said second guideway, a head formed on one endetsaid rod 'and proj-ecting into the path of Vsaid sleeve, said rod beingformed with'a plurality of spaced cirr cuinferential grooves and havingone side tlattened throughout' a portion of its length, and a headedscrew inounted'adjacent said rod, the head of said screw being adaptedAto enter selectively said grooves, said'l rod being rotatable to bringlthe flatside thereof into registry with said-screw head to ref lease thesaine from engagement in anyone of said grooves. j -Y 4.y In combinationwith a reciprocable member,l a limit stopy comprisinga rod mounted yinparallelism with" said member vand having a projection extending intothe path of said. member, one region inthe length of said rodbeingiormed with a plurality eli' spaced, circumferential grooves, andone side of said rod being the depth of said grooves in saidy region,and a headed screw adjustably `mounted'adjacent said rod, the headthereof being adapted to enter selectively said grooves',
